PART C: LEWIS DOT STRUCTURES Use the Lewis Dot structure rules on page 92 of this lab manual for the following: Write Lewis electron dot structures for each of these diatomic gases: valence electron 2(I 2 valence efectron-215)-10 H, N, valence clecton valence electron Covalent compounds (these are not charged chemical species): a (4098 valence electron # valence electron So CH, valence electron # valence electron : so, SO O, (not a cyelic molecule) valence clectron valence electron .: PCI,...
Worksheet 8.1“Lewis Dot Structures and Formal Charge Calculations” 1. Goal: Draw Lewis Dot Diagrams and determine either formal charge or bond polarity. 2. Why: to understand chemical bonding, you must be able draw three dimensional representations to show bond angles and strength of chemical bonds. Students also need to be able to use Calorimetry equations to calculate enthalpy of reactions. Atomic number (2) Chemical symbol Be1 9.01 - Atomic mass 3A 4A 5A 6A beryllium (defined in section 4.9) 13...
